Our workshop is well-equipped to service rotating machinery equipment with a quick turnaround time. We meet ISO 9001, OHSAS 18001 and IECEx service standard requirements. We are also the authorised and recommended service centre for companies such as GE, NOV and Leroy Somer.
Vacuum Pressure Impregnation (VPI)
Megawatts provides VPI treatment for motors. VPI is a process that uses vacuum and pressure to seal porous materials with varnish or resin. The process is used primarily for high-voltage motors and generators to fill gaps in materials to create a “void free” insulation that reduces motor failure drastically.
Why “old dip and bake” method is replaced by VPI process?
During baking, solvent varnishes lose 50% to 70% of volume, leaving voids and air pockets in the windings, making it more susceptible to damage and wear. The vacuum used in VPI creates a more solid structure that gives great mechanical strength, cooler running motor due to effective heat dissipation, and high level of environmental protection, withstanding against leaks, cracks, corrosion and moisture. A motor winding that undergoes VPI is virtually impervious to oil, moisture, and chemical contaminants.
VPI may be used for both A.C. and D.C. stators, armatures, field coils, and applications such as lifting magnets. Large frame motors from 460 volts through 13,800 volts should receive VPI, being a more cost-effective solution as it extends the lifetime of products while saving energy.
Approved Channel Partner of General Electric (GE) Motors
Megawatts workshop is the appointed authorised centre for supplying, servicing and repairing General Electric (GE) A.C / D.C. motors, meeting the technical and equipment requirements.
